SPRING-TIRE.

Specification of Letters Patent.

Patented June 16, 1908.

Application filed June 19,1907. Serial No. 379,787.

citizen of the United States, and a resident of the city of Elgin, county of Kane, and State of Illinois, have invented a certain new and useful Spring-Tire, of which the following is a specification.

My spring tire practically takes the place of the pneumatic rubber tire, because the same resiliency is had, but without any danger of puncturing, or blowing up, there are no valves to get out of order and the tire does not have to be inflated. There is no side-fleetion on springs, or tire and with a cover-plate the springs and working parts are kept free from dust, water and rust. l/Vhen once adjusted to a wheel for a certain purpose and is of proper weight and strength, nothing but ordinary care is required to keep said tires and springs in perfect order for an indefinite time. If perchance through accident or some defect, a spring should become broken, the defective part can readily be replaced by duplicateand perfect part or parts.

In'the accompanying drawings: Figure 1, represents assembled view of wheel, with springs attached to tire with a section of cover-plate removed. Fig. 2,. represents a view 'of a section of a wheel showing the springs and general arrangement and method of attachment. Fig. 3, represents asectional view of tire on line AA in Fig. 2, which shows the position and arrangement of coverplate, packing, and clips. Fig. 4, represents a sectional view, taken on line BB"in Fig. 2

and shows springs and alternating soft packing their position and their method of being bolted.

1, is a steel tire or outer rim.

2,, is soft packing or washer, between outer rim (1) and cover-plate (17 which is to keep out dust and water.

3, a soft packing, or washer, extending slightly beyond felly of wheel, against which cover-plate (17) rests or plays and, which also ilgto keep out water and dust, as shown in i l 3- 4, a steel tire 11 Outer edge offelly, round which packing 3) 'is'fast'ened.

5, 6 7 and 8 are four leaf sprin s, with soft packingor washers between eac spring as shown. at 9.. A less numberof springs and packing may he used if found mor'edesirable,

owingxte lightness of the vehicle-or-convey- I bolts (1 1) being run through said stee ance to which the wheel is to be attached and according to the use the same is to be put to the width and weight of said springs being governed accordingly. Also more springs and packing may be added in like manner when a heavier weight of conveyance or vehicle requires it. Springs and packings are applied alternately as indicated.

9, indicates leather washer, or soft packing between outer rim (1) and spring (5), likewise between springs 5 and 6, 6 and 7, 7 and 8, also between washer (10) and spring (8).

The same method is employed in fastening the set of springs to the outside rim (1), as to inside rim, or tire (4). Size and number of springs vary according to pressure and weight same will be subjected to.

10, is a steel washer with round or beveled corners, which is placed on top of spring 8,

(10), through the s rings and packings, through soft packing etween spring (5) and steel rim (4), through felly (12), through steel washer (13), with nut or bur on end. All springs bein lapped over at botto through which b0 t (11) passes.- r 13, is a metal washer as before described, resting on inside of felly (12) on bolt (11).

The outer portion of sprin s are held in place by countersunk head bo lts (14) which pass through steel tire 1) throu h the springs and washers, then through stee washer (10) with nut on end. 1

15, is steel clip bolted on inside of outer rim (1) with countersunk head bolts (16) to which cover-plate (17) is bolted.

17, is steel cover-plate on each side of springs, firmly resting in recesses in rim (1) and against packing (2) and against edge of washer a packing (3) and extending in this manner around entire wheel and extending inwardly toward hub of wheel far enoughto'insureprotection to rims and sprin s while in action. Said cover-plate (17 is 181d in place by round-headed bolts (18), which pass through holes (19) in clips (15).

I claim:

In a wheel, a felly, an outer rim, springs interposed between said felly and rim, a plurality of clips carried by the rim and formed with a portion extending transversely'of said rim and with down turned end portions, cover-plates secured to said downturned endportions of the clips, a packing, comprising a stri of soft material, interposed between posed between said springs and said felly and i J and extending beyond the sides thereof and sai cover-plates and said rim, and a packmy name in t e presence of two subscribing 111g, comprising a strip of soft material, inter- Witnesses. v
